I find that if I run in Terminal, it works well.

julia> cd("/Applications/julia/test/")

(test) pkg> activate .
  Activating project at `/Applications/julia/test`

julia> using CSV

julia> using DataFrames

But when I run in Atom REPL, it gets an error.

julia> cd("/Applications/julia/test/")

(@v1.7) pkg> activate .

So maybe it is the problem of Atom.

In vscode, it also works well.

Hmm, odd. Atom / Juno does somehow influence precompilation, but I’ve never quite understood how

@Raymond - do you use Atom? If yes - this is for sure Atom issue. Atom is not maintained and it is a known issue. Please switch to VS Code.

Yes, I switch to vscode.
